The Transportation Safety Board of Canada (TSB) has provided new details about its investigation into the crash of Endeavor Air flight 4819 at Toronto Pearson International Airport last February.
Although the update from the TSB provides few substantive details on the findings of the investigation, it details the work that investigators have been undertaking over the past year since the accident.
After the wreckage was brought to a hangar at the airport, key parts like the right wing (which detached after the aircraft landed), landing gear, and wing box structure were sent for further testing at the TSB’s Engineering Laboratory in Canada’s capital city of Ottawa. Analysis of the results of a metallurgical examination of the fracture surfaces on the wing and landing gear is currently underway.
Other pieces of key data have also been analyzed or reviewed, including data from onboard recorders, air traffic control systems, meteorological conditions, and the airport’s closed-circuit television systems. Investigators also attended Endeavor Air’s training facility to conduct similar exercises.
Once the TSB completes its analysis, it will draft a report and send it to key stakeholders. These parties have the opportunity to dispute or correct information before the board publishes a final report to the public.

February 2025 Accident Details
The accident occurred on February 17, 2025, when the CRJ-900 aircraft, operating as a Delta Connection flight from Minneapolis-St. Paul crashed upon landing. The right wing detached, and the aircraft flipped over. All 80 passengers and crew survived and were successfully evacuated from the aircraft, but 21 people were injured.
The TSB released a preliminary report in March of 2025, indicating that the aircraft had a “high rate of descent” of 1,110 feet per minute and a 7.1-degree right bank angle just before touchdown. According to the report, the right-side landing gear assembly fractured and folded, and the right wing detached, releasing jet fuel that caught fire. The aircraft slid down the runway and rolled to the right until it became inverted, stopping on an intersecting runway.
Since the accident, multiple lawsuits have been filed against Delta and Endeavor Air in relation to the incident.
